I've seen nmp split due to lateral movement and not deflection. If the sub floor moves enough nmp will go with it. Ditra and nmp would have worked on that job but like you say, who's gonna pay for both here!

Must have been a pretty shocking floor. I can't see there being much lateral movement in your average floor board or chipboard bathroom or kitchen.

That's the thing, it wasn't. No sign of deflection at all before or after the nmp and tiles split.

Hi Hm,
That's a first,
I use nmp and hb all the time & never had any issues.......
Just out of interest what was the subfloor you layed nmp and tiles onto as I'm baffled by this??
Thanks

Green chipboard. It was a first and only for me too. Some cracks appeared in the decorated walls as well. Must have been some structural movement. Not a new build either. Used tons of nmp too.
Replaced cracked tiles and board for free and the customer didn't offer me anything. Not even a brew!

Crikey mate,
Gotta have been structural movement then , so when you took up the area of tiles and nmp had the chipboard been affected??

It's defo a fail safe if we could nmp or hb and also decouple with real problematic floors but when the next fixer comes in at half your price you lose the job......oh man!....can't win!......I have suggested this on numerous occasions and I just get the raised eyebrow or 'no that's going too far'.........so I just quoted for a 60m2 floor kitchen diner, ....very expensive tiles had been purchased, so at present half or the area has been tiled and its failed - ( cracks , debonding, etc ) & half laminate which is also not great, very loose & a lot of movement there......so I've took a few tiles up and not surprising it looks as tho the previous fixers have used a 2 part adhesive onto the floorboards & it's gone **** up.....took some of the laminate up too & everywhere is floorboards.......so I suggested over boarding with 9mm nmp stuck down staggered glued with polyurethane adhesive under and where boards butt together and screwed and also just to be safe Bal rapid Matt.......I didn't get the job , another tiler came in £1500 cheaper than me..........

Cheeky gits could of at least made a cuppa
At least you had the decency to do the repair, some fixers wouldn't bother!

That's the game we're in unfortunately. When the cheaper guys work goes wrong you'll get the call. Try not to smile and say I told you soot

Tiling straight onto floor boards is something I wouldn't dream of doing, I wouldn't decouple on them either. So, in the real world, when is decoupling an absolute must do for you?

Ufh, screed & limestone tiles, advised them to Ditra but wouldn't listen.
Been to repair this twice, full floor needs ripped up & redone.

I hope you charged them well for the repairs? Especially as they didn't take your advice.
S

Made a fortune off of that job, don't work for the company now so it's nowt to do with me.
Told the guy the last time I spoke to him that the full place needs ripped up & redone.
F
Flintstone
Did you tile over all them cracks in the first place?
S
Stef
They weren't there when we started the job, most of the floor had slc down on it as its one of the worst poured floors I have worked on.
Advised that they must use a decoupler but they wouldn't listen so it got tiled as is.
This company never learn, they still overboard with 6mm ply.

Ive always plied wooden floors and just primed screeds
S

It can but I wouldn't tbh.
I would use Anhyfix for that job & tile away after testing & sanding the screed.
Was tested and sanded but do not have access to anhydride.
S
Stef
Anhyfix from TileMaster, brilliant adhesive to use.
It's a gypsum compatible adhesive specifically designed for calcium sulphate screeds.
S
Stef
This is it.
I'll look out for it, I haven't come across it here in Ireland is it expensive?
S
Stef
Depends where you get it from but round about the £20 mark.
